Abstract

A Comparative assessment of a cascaderefrigeration cycle with different refrigerant pair is presented in this paper. R744 is used in Low-temperature (LT) cycle whereas R134a, R290, R717 and R404A (R125(44%)/R143a(52%) /R134a(4%)) are used in the High-temperature (HT) cycle. The effects of the thermodynamic parameters on the cascade system are evaluated with an objective to find the best working fluid pair based on COP. R744-717 is selected based on thermodynamic and environmental performance. A parametric evaluation is also presented for R744-R717 working pair by varying parameters like sub cooling, superheating, evaporating, condensing temperature and temperature difference in the cascade condenser of the system.
